Ibicuruzwa:
1.Umweru wera cyangwa umuhondo muto ucyeye ufite uburyohe bwa aromatic. Kubora mumazi; Ethanol; ether na chloroform, nibindi, bitajegajega, byangirika iyo bikorana na alkali cyangwa bitandukanijwe numuvuduko wikirere. Ntabwo ihindagurika, ibora iyo ikorana na alkali cyangwa ikarishye kumuvuduko wikirere.
2.Ibicuruzwa ni uburozi buke, kumira ibicuruzwa birabujijwe rwose, uyikoresha agomba kwambara ibikoresho birinda.
3.Imiterere yimiti: Inzoga ya Diacetone irimo karubone na hydroxyl muri molekile, hamwe nimiti ya ketone na alcool ya gatatu. Kubora bibaho iyo bishyushye kuri 130 ° C cyangwa hejuru ya alkali, bikabyara molekile 2 za acetone. Iyo ashyutswe na acide sulfurike cyangwa urugero rwa iyode, iba idafite umwuma kugirango ikore isopropylidene acetone. Imikoranire na sodium hypobromite itanga aside-hydroxyisovaleric. Hydrogenation ya catalitiki itanga 2-methyl-2,4-pentanediol.
4.Ibicuruzwa birakaza amaso, uruhu hamwe nuduce twinshi two mu myanya y'ubuhumekero. Yinjira mu mubiri binyuze mu myanya y'ubuhumekero no mu gifu, bigira ingaruka ku mitsi no kwangiza umwijima n'igifu. Guhumeka umwuka mwinshi wumuyaga birashobora gukora ibihaha ndetse na koma. Kumara igihe kirekire bishobora gutera dermatite.
5.Fata muguteka itabi, itabi ryimbavu ryera, itabi ryibirungo, numwotsi w itabi.
Gusaba ibicuruzwa:
1. Inzoga ya diacetone irashobora gukoreshwa nkisukura ibyuma, kubika ibiti, kubungabunga firime zifotora nibiyobyabwenge, antifreeze, ibishishwa byamazi ya hydraulic, ibiyikuramo nibisohora fibre.
2. Inzoga ya Diacetone ikoreshwa cyane nk'umuti wo gusiga amarangi ya spray ya electrostatike, selile, nitrocellulose, amavuta, amavuta, ibishashara hamwe na resin. Inzoga ya Diacetone ni ikintu kinini gitetse kama. Ubukonje buri hasi kandi ingaruka zubushyuhe kumitsi ni nto. Ikoreshwa nka solvent na irangi ryerekana irangi rya selile ester irangi, irangi ryo gucapa, irangi rya resinike.
3.Bikoreshwa cyane nk'umuti wa resin, amarangi ya spray ya electrostatike, selile, fibre ya nitro, amavuta, amavuta n'ibishashara. Ikoreshwa kandi nk'isukura ibyuma, kubika ibiti, kubungabunga firime zifotora nubuvuzi, antifreeze, amavuta ya hydraulic amavuta, imiti ikuramo na fibre. Nubwoko bwa synthesis synthesis.
4.Imiti yo kwisiga, ikoreshwa cyane nka poli yimisumari hamwe nandi mavuta yo kwisiga yumuti muremure. Mubisanzwe byateguwe hamwe nuduce duto two gutekesha hamwe no gutekesha hagati yo gutekesha mumashanyarazi avanze, kugirango ubone igipimo gikwiye cyo guhumeka hamwe nubwiza.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe, irinde izuba ryinshi.
3.Komeza ikintu gifunze.
4.Ntibishobora kwangirika kwicyuma, kandi birashobora kubikwa mubyuma, ibyuma byoroshye cyangwa ibikoresho bya aluminiyumu, ariko bigira ingaruka mbi kumoko menshi ya plastiki.
5.Bika kandi utware mu bwigunge ibintu bya okiside na aside.
6.Indobo cyangwa icupa ryikirahure cyuzuyemo agasanduku k'ibiti.
